possible bug?

[eeyem u washington edu]

I've encountered an inconsistency in GTK+ that may be a bug.
I want to verify I'm not doing anything wrong, before I submit a bug report.

I want to attach a popup menu (via the button-press-event) to a few controls.
When I use the same code on a GtkEntry and a GtkButton, I must click on menu
items *twice* before anything happens on the GtkEntry.  With the GtkButton,
it works as expected (one click).

I've attached a sample program, exhibiting the behavior.
